4.1 The thermal resistance of a ceiling system is used to characterize its steady-state thermal performance. 4.2 The thermal resistance of insulation is related to the density and thickness of the insulation. Test data on thermal resistance are obtained at a thickness and density representative of...
1.1 This test method shall be used to measure the relative corner impact resistance and other damage that may occur during the rough handling of wood-base panels or composite materials. This test method is suitable for all wood-base panels such as plywood, oriented strand board, hardboard,...
This specification covers prefabricated, self-adhesive, polyester fabric reinforced, polymer-modified asphalt surfaced roll roofing products, with granule surfacing, designed for steep slope applications. These products use polymer modifiers in their top and bottom coatings and have an adhesive...
1.1 This specification provides the means to measure and evaluate the performance of adhesives for structural or semi-structural bonding of wood-to-wood in manufactured homes. Wood as used in this specification includes lumber, plywood, particleboard, gypsum board, and all materials having...
1.1 This test method provides a procedure to determine the quality of bond between an overlay and a wood core in an adhesively bonded laminate. The quality of bond is determined by measuring the resistance to delamination of the adhesively bonded laminate when tested under specific conditions of...
1.1 This specification is applicable to the use of plastic lumber materials and of wood-plastic composite materials, and no other plastic composite materials, used as exterior wall coverings, as part of an exterior wall assembly. 1.2 This specification is not applicable to the use of plastic lumber...
1.1 This test method covers the determination of comparative shear properties of gap-filling adhesives in wood-to-wood joints at specified thicknesses of bondline in the dry condition, when tested on standard specimens under specified conditions of preparation, conditioning, and loading in...
1.1 This specification covers polyvinyl acetate or polyvinyl acetate copolymer resin emulsion adhesives suitable for use on wood, wood-based substrates, or plastic laminates. It does not cover the group of polyvinyl-based adhesives which are suitable for bonding flexible films. 1.2 The adhesives...
1.1 This test method covers determination of the shear modulus of wood-based structural panels associated with shear distortion in the plane of the panels. The method is applicable to all types of wood-based structural panels. The grain direction or orientation of the individual plies, laminations,...
4.1 This practice covers procedures of sampling for obtaining small, clear wood specimens which, when tested in accordance with Test Methods D143 and, in conjunction with full-size product tests, will provide mechanical properties for use in deriving design properties for lumber, panels, poles,...
1.1 This test method covers a small scale procedure for measuring formaldehyde emission potential from wood products under defined test conditions. The formaldehyde level is determined by collecting air-borne formaldehyde in a small distilled water reservoir within a closed desiccator. The quantity...
1.1 These test methods cover procedures for planing, routing/shaping, turning, mortising, boring, and sanding, all of which are common wood-working operations used in the manufacture of wood products. These tests apply, in different degrees, to two general classes of materials: 1.1.1 Wood in the...
QUALIFIED PRODUCT LIST OF PRODUCTS QUALIFIED UNDER PERFORMANCE SPECIFICATION MIL-L-19140 Lumber and Plywood, Fire-Retardant Treated This list has been prepared for use by or for the Government in the acquisition of products covered by the subject specification and such listing of a product...

5.1 This practice establishes the procedure to determine adjustment factors that account for the isolated effects of fire-retardant treatment on plywood roof sheathing. These effects are established relative to performance of untreated plywood. This practice uses data from reference...
5.1 The impact sound rating for a floor assembly is determined both by the basic floor assembly and the floor covering on the upper surface. The same floor covering in combination with different basic floor assemblies will not always give the same impact insulation class (IIC) ratings. This test...
This document establishes general rules for the classification of plywood by its surface appearance. It concerns plywood made of hardwood including tropical and temperate hardwood, softwood and plywood derived from other lignocellulosic materials. It does not apply to overlaid...
1.1 This specification covers polymer modified bituminous sheet materials intended for use as underlayment on roof eaves, or valleys, or both, to prevent leakage of shingle, tile, or metal roofs from water back-up due to ice dams. 1.2 These underlayment sheets have a sticky adhesive layer which is...
This document recommends the industrial standards to be applied to the treatment of timber to attain a fire-retardant finish and lists the most commonly used and available timber species. Advice from the Wood Protection Association (WPA) has been used in the preparation of this defence standard....
This document specifies the nature and limits of characteristics inherent in wood and manufacturing defects enabling the visual assessment of the plywood for allocation to an appearance class. This document applies to plywood, the surface veneers of which are made from hardwood...
